Add/remove files from a project

[#1]

I have noticed in the DAVE project window that this seems to be arranged as the files are arranged in their disk folders. I cannot see a way to, say, remove a file from a project without deleting it from the actual folder. Most IDE project systems allow a mechanism to add/remove files from a project without physically deleting or adding it from disk but I can't see a way to do this with the DAVE projects? Incidentally I wish to do this because I am working with both GCC & Keil compiler and they have different startup files.

You can do this as follows:
Right mouse click on the file you want exclude:
->Resource Configurations -> Exclude from Build

Then the file will be removed from build process but is still visible (with changed file icon).

That works a treat - thank you. Although the changed file Icon is only visible in the project explorer window it is still useful,
